18-channel DIY Stereo Analog Vocoder

[jfloftin]

I received my package. I now need to save up for the rest of the items. I am a Mac user. The BOM sent to us was created with the Windows version. Stephan and I tried multiple times and I found out that Windows and Mac versions of Office will not allow macros to work. Could someone here on the forum send me a Mouser BOM?

Thanks!

Hi jfloftin,

use the BOM PDF from Stephan,

http://vocoder.hoerold.com/Misc/Vocoder%20BOM.pdf

Is it that what you need?

Cheers Bernhard

I looked at that 50+ page document. I want a link to a full BOM on Mouser if someone could do it for speeds sake. I have an account with Mouser and have been purchasing from them for years. Farnell seems to be too European for me since I live in the US. Thanks anyway Bernhard...

I seen the issue on my Mac and can confirm that Microsoft office is not 100% computable across platforms. You can open the document in Libre Office or Google Sheets without error.

The Mouser links are on the first post of this thread...

You will need to source a few things elsewhere due to stocking issues or substitute. I also recommend that you look at the price breaks, you may buy 10 and need 2 for less sometimes.

Note: the bundle I am offering is not the whole kit. You will still have to order parts from your trusted distributor. There are three Mouser projects available:

• 18-channel stereo vocoder (excl. supply). This is the vocoder BOM, excluding the components needed for the power supply.
• Vocoder DC/DC supply. This covers components available at Mouser for the DC/DC converter based power supply.
• Vocoder LDO supply. This covers components available at Mouser for the alternative LDO based power supply.

Email/PM sent!

[A.S.]

has this gone and won't it ever return?
i am very impressed with the vocoder - as far as soldering goes, i can do central heating, hot and cold running water, but i would really like to have one built.....

i really hope there will be another chance to either buy the kit or a ready made vocoder. the sound really reminds me of some of the best vocoders.

@A.S. well, I got my kit.
Have you tried sending glubsch an email? vocoder@hoerold.com

I haven't started building mine yet. I'd be willing to make two at the same time...soldering projects is my happy place.

The only issue is that glubsch does them in batches...so getting pcbs might be an issue, unless there is someone else with a languishing kit.

[Flounderguts]

I decided to start my build...

I have a unique situation with parts, and I just spent a couple of hours pulling those (80!) values of unique resistors. I have pulled enough for 2 sets...if anyone wants a full set of the resistors for the channel boards (not including the common values of 6.8k, 10k,20k,24k,27k,33k) I could provide that. PM me if you're interested!

[glubsch]

A.S. I sent you an email via muffwiggler. Not sure if you've received it.

been away for awhile...looks like i missed out on an interesting project!

Im getting close to having all the boards soldered up, but Im short the 36 MC33079Ps. Anybody know where to get them? Ive seen them on ebay / alibaba, but not sure if they would be legit.

I saw that we can use tl074's as a replacement but it adds additional noise. Any comments on how bad the noise is?

[Flounderguts]

Where are you located? If you're in Europe, several of the smaller vendors have them. If USA, then eBay or Amazon are your best bets, though you will pay $1.75 to $2.00 each. AliExpress is hit or miss with fakes...at least with Amazon you can send them back.

If you strike out, I can get my hands on more, I think.

[nobody]

Ok. I'll try Amazon and see what I get. Thanks.

Has anyone finished their build and demoed it? Just curious. Want to see a video of it.

Here are some shots of my build





And a couple of test recordings (sorry they aren't the best as I did them as a test whilst building, but it gives you an idea of some the features )

thank you for the samples

[wiperactive]

Yes thanks, nice to hear this apart from the official video demo.

I'm sure I'm not alone in delaying my build... lots of other simpler projects on the go and stalling a bit over the cost of all the additional components I still need to buy.

Can't see your photos though, even though I've tried different browsers etc.

[Flounderguts]

I found that chipping away at placing the cheap components (resistors!) is keeping me aware and interested...
The biggest hurdle for me is getting all the board-to-board connectors...but that can wait until xmas, maybe.

9 filter boards left to assemble...!

Looking forward to eventually seeing how yours looks and sounds... best wishes for a successful build!

In my case, I just hope I'm not in a care home surrounded by jigsaws and still trying to finish it.

updated pics above, hopefully you can see them this time

I made all the cables in one sitting just to get them out of the way before I built anything. It was nice to then just be able to plug them in as needed

[wiperactive]

Ooh nice!

Maybe I should have ordered the black panel after all? Anyway, I opted for aluminium though I'll probably settle for black or dark crimson knobs instead of the light blue of the demo unit... building it should be the easy bit

Super nice! I'm wiring mine together now.

Did you have any issues with the TLLR4401 leds? I followed the guide, but none of the LEDs worked. I figured out that they were reversed. The anode according to the data sheet is the long lead. The build guide says on the led connectors the anode should be on the left pin. Had to flip pins on the power supply board and it's working now.

[Flounderguts]

Getting closer on my build...

I'm almost finished the filter boards, and C41 is not mentioned in the BOM or on the build (that I can find in my current state!)
Is it also a 47uF electrolytic, as per C35-C40? The ss indicates an electrolytic.

Hopefully it's a different value...135x 47 uF is putting a strain on my stock!

EDIT:

Nevermind! A good night's sleep, and the answer was easy to find!
